EMIL NEUGEBAUER, OF WIESBADEN, GERMANY.

SIPHON.

To all whom it may concern:

Be it known that I, EMIL NEUGEBAUER, a subject of the German Emperor, and residing at 2 Schillerstrasse, Wiesbaden, Ger many, have invented certain new and useful Improvements in siphons, of which the following is a specification.

This invention relates to improvements in s1phons and the objects of my improvement are to provide an automatic siphon, that is to say a siphon which will become charged and will start automatically by the mere immersion of art of said si hon into a vessel containing 'quid which it is desired to cause to flow out of said vessel over the edge of said vessel in the manner of an ordinary siphon. I attain these objects by constructing the improved siphon with an inlet portion and an outlet portion, the inlet portion constituting a short siphon and the outlet portion constituting a arge siphon, the two ortions or siphons being connected in series y joining the outlet leg of the short siphon by a bend with the inlet leg of the long siphon, the top of the short siphon being sltuated at a lower level than the top of the long si hon, and the inlet of the short siphon eing situate at a higher level than the outlet of the long siphon.

In the accompanying drawings :Figure 1 is a side elevation, partly in vertical section of the improved siphon and Fig. 2 is a View showing the im roved siphon in side elevation on a sma ler scale in operation for em tying liquid from a tank into a receptac e, both the latter being shown in vertical section.

The improved siphon comprises what may be considered to be an ordinary siphon, c, a, b, bent round at the lower end, I), of its short leg and continued upwardly to form what may be considered also to be an ordinary siphon, b, d, e, shorter than the first mentioned ordinary siphon, that is to say, the top, at, of the siphon, b, d, e, is situate at a lowej; level than the top, a, of the siphon, c, a,

In operation, the improved siphon, c, a, b, d, e, is placed in the tank, 9, to be emptied, with its portion, 7), d, e, immersed in the liquid in the tank as shown in Fig. 2 so that the lower to d, of the siphon is situate beneath the leve of the liquid in the tank. The

lower end, 0, of the long leg, a c, of the improved siphon is situate below the bottom of the tank, g, and dips into a vessel, f, which receives the discharge of the siphon. As soon as the improved si hon is immersed as described the liquid in t e tank, g, enters the end, 6, of the shorter siphon, e d, b, as indicated by the arrow, and thus causes the said shorter siphon to come into operation. By this means the liquid flows down in the leg, d, b, and flows up in the leg, I), a as indicated by the arrows with an impetus such that its momentum will carry it over the bend, a, into the long leg, a c, of the siphon thereby charging and starting the whole siphon automatioally and thus causing a steady siphoning of the liquid from the tank, 9, into thevessel, f.

Having now described my invention what I claim as new and desire to secure by Letters Patent is 1. In si honic apparatus the combination of two siplions of equal diameters connected together in series by a continuous duct having the same common diameter as the said siphons, the top of the first siphon being situated at a lower level than the to of the second siphon, and the inlet of the s iort leg of said first siphon being situate at a higher level than the outlet of the long log of said second siphon, whereby the said a paratus constitutes a self-charging and sel -starting siphon on immersion of said first siphon into the liquid to be siphoned over.

2. In a siphon t e combination of a longer siphon, a shorter siphon and a bend connecting the inlet leg of the longer si )hon with the outlet leg of the short siphon, w iereby on immersion of the shorter siphon in liquid, the

combined si hon will charge itself automatic-- ally and wil start automatically to dischar e the liquid by siphonic action, as set fort 1.

- 3. In a si hon, the combination of a long leg, a short leg, and an inverted siphon portion connected at one end with a bend to the to of said long leg, and at its other end with a end to the top of said short leg, the bend at the top of the long leg being situate at a higher level than the bend at the top of the short leg, whereby the siphon is rendered self-charging and self starting by immersion of the short leg in the liquid to be siphoned over, as set forth.

4. Asiphon in which the shorter leg is bent 5 In testimony whereof I have signed my up at 1ts lower end and eontlnued to a polnt name to thls speelhcatlon 1n the presence of sltuated at a lower level than the top of the two subsenbmg wltnesses.
